Making invisible Ink


Making invisible ink is a lot of fun ; we can keep all our secrets codes and messages hidden from others . All we need is some basic household obejects and the hidden power of lemon juice .


We need just a half lemon ; water ; spoon ; bowl ; cotton bud ; white paper ; lamp
We start by squeezing some lemon juice into the bowl and add a few drops of water , then we mix the water and lemon juice with the spoon , we dip the cotton bud into the miwture and write a message onto the white paper . We shall wait for the juice to dry so it becomes completly invisible , and when we are ready to read the message or show it to someone else , we heat the paper by holding it close to a lamp . we explain that the lemon is an organic substance that oxidizes and turns brown when heated



this is a simple experiment
